C'est rien de nouveau, c'est un setup turbo sequentiel. Un petit turbo pour spoolé vite @lowRPM pi un gros turbo pour avoir du boost @highRPM.
 
You guys should click and read sometimes: It's a sequential turbo, yes, but with a twist

According to the filing, typical two-stage turbochargers are configured to operate both turbines simultaneously at low/mid engine speeds, while at high engine speeds, only the low-pressure turbine operates. The issue with this design is it can never completely isolate either the low or high pressure side, forcing inlet design compromises, which in turn can impair low end performance and result in higher pumping loses. GM’s new system proposes to eliminate the compromise.

I have a gut feeling this will be used in GMCs diesel trucks. Article thinks its for the upcoming cadillacs but i dont think so.

C'est pas juste un setup sequentielle. Il élimine le compromit creer par le principe d'avoir 2 turbo séquentielle.
